With reference now to FIG. 1, a diagram of an irrigated field 101 with aplurality of watering wheel irrigators 103 a-103 n thereon is shownaccording to one embodiment of the present technology. In general,watering wheel irrigators 103 a-103 n are used within field 101 toirrigate a circular area such as circular areas 102 a-102 n. Although 4watering wheel irrigators 103 are shown in field 101, it should beappreciated that a field 101 may consist of more or fewer watering wheelirrigators. The use of 4 watering wheel irrigators herein is merely forpurposes of clarity. Moreover, it should also be appreciated that afield 101 does not have to be rectangular but may be of any shape. Forexample, in one embodiment circular area 102 may be a field 101.

Referring now to FIG. 2, a top view diagram of a field 102 with a singlewatering wheel irrigator 103 thereon is shown according to oneembodiment of the present technology. In one embodiment, watering wheelirrigator 103, includes a pivot 205, a water conveyance 206, such as atube, gutter, hose or the like, and wheels 204 a-204 n to support thewater conveyance 206.

Conversely, in a large field101, watering wheel irrigator 103 may be 100-600 feet long. Although anumber of sizes are described, the actual size of watering wheelirrigator 103 may be outside of the stated ranges in either direction.The watering wheel irrigator 103 lengths herein are merely provided forclarity.

In one embodiment, watering wheel irrigator 103 also includes an antenna310 and a plurality of moisture sensing probes 308 a-308 n. As can beseen from the illustration, each wheel 204 may have none or any numberof moisture sensing probes 308 affixed to the wheel 204. For example,wheel 204 closest to pivot 205 is shown with 4 moisture sensing probes308, while the second wheel 204 has 2 moisture sensing probes 308 andthe third wheel is shown with 3 moisture sensing probes 308. In anotherexample, the moisture sensing probes 308 may be placed only on everyother wheel, every third wheel, or the like.

For example, a shorter body 360will provide a measurement closer to the ground 325 surface while alonger body 360 will provide a deeper soil moisture content measurement.

Converter 363 is utilized to convert the moisture content measurementfrom the water sensor 365 to an electronic signal indicative of themoisture content of the soil. The electronic signal can then betransmitted over data path 355. In general, data path 355 may be wiredor wireless.

In one embodiment, watering wheel moisture determiner 500 also includesa moisture content converter 363 to receive the moisture sensinginformation and convert the moisture sensing information into a signalindicative of the moisture content of the ground 325.

Watering wheel moisture determiner 500 includes a moisture contentprovider 357. In one embodiment, moisture content provider transmits thesignal indicative of the moisture content of the ground 325 in a useraccessible format such as, moisture content report 540. In oneembodiment, the moisture content provider 357 is located at the at leastone wheel 204; However, in another embodiment, the moisture contentprovider 357 is located at the central pivot 205. For example, moisturecontent provider 357 may include a transmitter to transmit the datawired or wirelessly.

Referring now to FIG. 6, a flowchart 600 of a method for determiningground moisture is shown according to one embodiment of the presenttechnology.

With reference now to 610 of FIG. 6 and FIG. 3, one embodiment couplesat least one moisture sensor 308 with at least one wheel 204 of awatering wheel irrigator 103. As stated herein, each wheel 204 may havenone or any number of moisture sensing probes 308 affixed to the wheel204. For example, wheel 204 closest to pivot 205 is shown with 4moisture sensing probes 308, while the second wheel 204 has 2 moisturesensing probes 308 and the third wheel is shown with 3 moisture sensingprobes 308. In another example, the moisture sensing probes 308 may beplaced only on every other wheel, every third wheel, or the like.

With reference now to 620 of FIG. 6 and FIG. 2, one embodiment rotatesthe watering wheel irrigator 103 about a central pivot 205.

With reference now to 630 of FIG. 6 and FIG. 3, one embodiment utilizesthe at least one moisture sensor 308 to determine moisture informationcomprising the moisture content of a portion of ground 325 proximal tothe at least one wheel 308 at different points during the rotating 210of the watering wheel irrigator 103 about the central pivot 205.

In one embodiment, the moisture sensing probes 308 are affixed to thewheel 204 and punch into the ground 325 as watering wheel irrigator 103rotates about pivot 205 through the field 102.

With reference now to 640 of FIG. 6 and FIG. 5, one embodiment providesa moisture information converter 363 to convert the moisture informationfrom the at least one moisture sensor 308 into a moisture content report540. In one embodiment, the moisture information is collected from eachmoisture sensor 308 at a moisture information converter 363 coupled tothe moisture sensor 308.

In another embodiment, the moisture information is collected from one ormore moisture sensors 308 at a central moisture sensor data collectionlocation. For example, each moisture sensor 308 may be wired orwirelessly coupled with a central moisture information converter 363.The central moisture information converter 363 may be located at thewheel 204 or at another location on the watering wheel irrigator 103.

In one embodiment, a transmitter/receiver 310 located at the centralpivot 205 is used for transmitting the moisture content report 540.However, in another embodiment, a transmitter may be incorporated atdifferent locations on the watering wheel irrigator 103, such as atwheel 204 for transmitting the moisture content report.

In one embodiment, moisture content report 540 is used as stand-aloneinformation. For example, the moisture content report 540 may provideinformation about over-watering or under-watering situations for aparticular field. However, moisture content report 540 may be mined downfor further specific information. For example, if more than one wheel204 a-204 n has a moisture sensing probe 308, the information frommoisture content report 540 could be used to determine differentmoisture issues within the circular area 102. In other words, if one ormore sprinklers 305 were clogged or miss-operating, moisture contentreport 540 may show that the ground is well-watered except for the areaaround wheel 204 a. If the area around 204 a was shown as beingoverwatered, a leak or the like may be occurring. Similarly, if theground around 204 a was shown as being under-watered, sprinkler 305 amay be clogged, broken, or the like.

In another embodiment, moisture content report 540 may be used by alarger field management system. For example, moisture content report 540may be added to a database of information that can be used to developwatering plans and schedules to meet the needs of the crops, as definedby agronomists, or the farmer. In another example, moisture contentreport 540 may be used to estimate watering needs based on crop, fieldparameters, time of year, weather, desired water content for the soil,and the like. Additionally, the larger field management system may usemoisture content report 540 to provide manual adjustment recommendationsor even perform automatic adjustments to the watering wheel irrigator103.

For example, after receiving the moisture content report 540, the fieldmanagement system may modify how long the watering wheel irrigator 103is on for at a given flow rate, if the flow rate can be adjusted, andthe like. In other words, in one embodiment, the signal is used toautomatically control the amount of water disseminated by the moisturesensing watering system.
